The man Modesto police hired to search part of San Francisco Bay with sonar now believes he found Laci Peterson's body in mid-March.

But the officer who led the search disputed published reports Sunday that divers saw the body of Peterson, the pregnant Modesto woman reported missing Christmas Eve.

Peterson's body washed ashore near Richmond on April 14, a day after the remains of her unborn son were discovered about a mile away.

The Modesto Police Department had hired Gene Ralston of Idaho to search the bay with side-scan sonar. He now believes that what he saw March 13 was Peterson's body, based on where she was found.

"Piecing all the information we have now, I believe it probably was Laci Peterson," Ralston said.

So that's what images look like with sonar. Thanks. I am pretty sure I've been on boats that use sonar to find the schools of fish and thought it would only track movement.
